Many have developed customized cognitive training programs based on screening strategies that assess cognitive functioning prior to training.

  • the basic principle behind the present innovation is to use mathematical algorithms for each cognitive task and to use them on a computerized system in order to adjust specific task parameters from trial to trial and hence to adjust and personalize the difficulty of each cognitive task during training.
  • Cognitive training sessions are built into several discrete trials, each trial requiring a response, action or answer from the user.
  • the system may modify stimuli parameters from trial to trial to ensure fast adjustments of task difficulty to user's fluctuating performance and skills and maintain user in optimal training range.
  • the system may use the latest trial parameters (124) along with the response(s) made by the user in the last, and/or up to the four last (102, 104, 106, 108), trials in order to modify the stimuli parameters of the next trial 120 and so on for the entire training session, as shown in Figure 1. It is to be understood that the number of trial used to adjust the task difficulty may vary. In the present example, the responses of four trials are used but it may be more or less than four trials.
  • the user's response is collected and scored as success or failure (1 10, 112, 1 14, 1 16).
  • the system records and stores the responses and their sequence, and adjusts the presentation of stimuli in order to adapt the task difficulty (120) so that the overall percentage of correct answer for the trials will be within an optimal training range of approximately 65 % to 85 %.
  • the present invention is not restricted to this training range and those skilled in the art would know that performance of about 75% correct answers represents the optimal training range conventionally employed in cognitive psychology training.
  • the data associated to this session are updated (124) so that they will be used to determine the task difficulty of the next trial.
  • the system For each cognitive task, the system stores the responses and task parameters of each trial onto a permanent memory storage device (locally or on a server).
  • the data from previous sessions' responses and task parameters may be retrieved (202) and may be used to start a subsequent training session of the same and/or a different exercise, allowing the system to provide for personalized task parameters that already are compatible with a user's optimal training range, as shown in Figure 2.
  • the system determines, for a particular user, if there are data recorded from previous trials (202). If there are previous data available (204), the system uses the previous parameters (206) for the current trial.
  • the system adjusts task parameters from trial to trial in direct relation with the series of responses made by the user. This allows to rapidly increase or decrease task difficulty, to reach the optimal training range within a few trials depending on the user's aptitude for a given task, and to maintain the task difficulty in the optimal training range even if the user's ability fluctuates during the training session.
  • the present invention is distinct from other methods employed to customize cognitive training and presents many advantages.
  • One of the most important challenge with cognitive training programs is to ensure interest and motivation to carry on training. Too easy or too difficult tasks would lead to loss of interest, loss of motivation, training withdrawal and abortion.
  • an approach providing a rapid adjusting method to attain a user's optimal training range increases motivation and interest which in turn favours better compliance and outcome to the training.
  • Some existing approaches are based on preliminary testing of cognitive functions using home-made or third party screening tests.
  • the results of this preliminary testing determine the level of difficulty, and/or the type and/or sequence of tasks, of the trials and sessions that will thereafter be presented to the user during the session.
  • This approach has two main pitfalls. First, oftentimes we design pre-test trials that are not strictly similar to the task to be accomplished during the training session. Under these circumstances, the validation of the correspondence between testing and training tasks is unknown. This means that, for a given psychological process, the task employed for training may not be fully comparable to the test used during preliminary screening thus leading to inadequate training of this given process. [0056] Second, this kind of approach is vulnerable to many artefacts as multiple variables may influence performance during screening testing.
  • the method employed in the present invention is much more straightforward and adaptable compared to the aforementioned approaches. Depending on the type of cognitive task and the performance level of a user, it may require in most users from 3 to 15 trials to attain the optimal task difficulty range. This is a major issue regarding cognitive training as it ensures interest and motivation to continue training at the most appropriate level.
  • Another challenge with cognitive training is the need to customize task parameters and difficulty to the actual user due to broad disparity in inter-individual cognitive capacities.
  • the method used in the present invention ensures that a broader variety of users may reach their optimal training levels. Even those with important cognitive difficulties or those gifted with aptitudes would be able to achieve a customized training level.
  • Cognitive domains listed are namely, but not limited to, perceptual functions, motor coordination, attentional skills, memory aptitudes, executive functions, visuo- spatial processing skills, arithmetic and linguistic abilities.

  • the present invention may be used to train visual and auditory perception skills and/or temporal perception.
  • the stimuli parameters modified by the system may include absolute and/or relative differences in the psychophysical properties between target and interfering stimuli such as: object shape, size, border type, location, color, speed, direction, blur, salience, number of objects, sound frequency, sound and/or light intensity, similarity of stimuli, temporal distance, and/or presentation time.
  • the system may present an arrow pointing in a precise direction along with multiple stimuli objects moving in different directions and at different speeds.
  • the user may be asked to identify the object that moves in the same direction than the arrow or may be asked to identify the one that moves slower than the others.
  • the system may adjust objects' speed and/or direction from trial to trial based on the latest parameters employed in order to obtain a success rate approximately between 65% and 85%.
  • This method allows fast increases or decreases of the relative difference between the target stimulus' speed and/or direction compared to those of the interfering stimuli and hence, to rapidly increase or decrease task difficulty to adapt it to the fluctuating optimal training range of the user for this training skill.
  • Motor coordination is the capacity to physically interact with moving stimuli presented in the environment.
  • the present system may be used to train motor coordination in response to visual and/or auditory stimuli by moving the cursor via a computer mouse in response to a moving object seen on the screen or to a sound heard that changes its frequency and/or intensity.

Another way to train memory would be to present the user a sequential list of cards showing drawn objects. After the list is shown, the user is then presented with two cards at a time and asked to indicate which of the cards was presented first in the list (if both cards shown were in the list) or which card was not presented in the list (if only one card was shown in the list).
